TYPE NKSⅡ-RB

■ SPECIFICATIONS ① Centrifugal multiblade fan ② Suction Gas temperature limits -10～60℃ ③ Shaft seal is gland sheet type


・NKSⅡ-RB is made from injection fabrication FRP, this fan is durable against corrosive gases.

・The NKSⅡ-RB coordinates rotational speed with belt drive to adjust required performance, making it economical to operate.

・This design makes this fan highly efficient, and reduces noise.

TYPE NKSⅡ-O

■ SPECIFICATIONS ① Centrifugal multiblade fan ② Suction Gas temperature limits -10～60℃ ③ Shaft seal is gland sheet type


・NKSⅡ-O is made from injection fabrication FRP, this fan is durable against corrosive gases.

・The NKSⅡ-O is high efficiency than belt drive. ・If inverter control is used, the rotational speed can be

set easily. ・Since consumables are only a motor, maintenance is easy. ・This design makes this fan highly efficient, and

reduces noise.
